Yes this is true, but if you were to price the complete (already built) version of the light changer, you would see that you can build it for thousands of dollars less than you can buy it for. If you have not used one, just say so. Last I checked this is an electronic project page, not a page to question legalality of items that you don't agree with. I would be willing to bet that although you preach about legality, probably about 85% percent of the electonic persons who read this page know how to steal cable, and are probably doing so right now (maybe even you).
